unsatisfy_() compared positional total/inuse/wanted arrays (entry i is
resource wanted->idxs[i]) with uncomitted[i], but the allocation
context's uncommitted vectors are dense and keyed by resource index.
From the second primary of a COMPOUND/ALTER job on, the check ignored
earlier primaries' claim on the same resource (over-admit) or charged
another resource's (wrong pend), with the matching wrong shortfall in
the pend reason.
unsatisfy_() now takes the vector and reads entry wanted->idxs[i]; an
index past its end (sim_loop.c's short all-zero vectors) or a NULL
vector counts as nothing uncommitted.
